In Iraq, at least 20 people were killed and 34 others injured after a suicide bomber blew himself up in a market in the town of Musayyib, south of Baghdad, today. A source at Musayyib hospital said at least four of the wounded were in very serious condition following the blast. <br/><br/>The attack in Musayyib came hours after another, apparently failed attack in the Shiite shrine city of Karbala, a few kilometres to the southwest. Police sources said both attacks were claimed by the Islamic State IS group. <br/><br/>The bombings in Baghdad came as Iraqi forces fight to retake the last IS-held areas of Mosul, a city that was the IS group's emblematic stronghold. Iraqi forces are almost eight months into a massive operation to recapture the second city and have already taken back its whole eastern side and much of the west.
